Which division of the nervous system is responsible for the changes in heart rate and respiration Frank has experienced?

The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response.

Which of the following are components of the peripheral nervous system?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

Which system is responsible for decreasing heart rate?

The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.

How the central nervous system works?

The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.

How does autonomic nervous system work?

The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing. This system works automatically (autonomously), without a person’s conscious effort. Disorders of the autonomic nervous system can affect any body part or process.

What activates the autonomic nervous system?

The autonomic nervous system is one of the major neural pathways activated by stress. In situations that are often associated with chronic stress, such as major depressive disorder, the sympathetic nervous system can be continuously activated without the normal counteraction of the parasympathetic nervous system.

How does the peripheral nervous system work explain?

The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment. The nerves that make up the peripheral nervous system are actually the axons or bundles of axons from nerve cells or neurons.

How does the peripheral nervous system function?

The PNS connects the CNS to the rest of the body. The primary function of the peripheral nervous system is to connect the brain and spinal cord to the rest of the body and the external environment. The peripheral nervous system transmits information to and from the CNS.

Why does a ball pen have a nib?

For ball pen,ball pen at its nib there exists a small ball present which moves as we use little pressure the ball revolves accordingly and due to its surface tension of the ink gets disturbs the ink flows this happens in a ball pen.

What makes a ball point pen dry up?

Most pens just have cheap ink, bad ball bearings, or dry up. Sometimes the paper you use has impurities that gum up the ball bearing, especially if you’re the type to press down hard on the pen while writing. These things happen. The best solution if hand writing is a priority is to stop using cheap pens and invest in a proper fountain pen.

Why does the hand pull away from the hot pot?

This occurs when the motor neurons deliver nerve impulses from the spinal cord to the part of the body where a response to the stimulus is needed. In the above example, the response is the muscle contraction to quickly pull the hand away from the hot pot.

What happens to nerve impulses in the spinal cord?

At the point of contact with the hot pot, skin receptors quickly send nerve impulses (electrical) to the spinal cord (central nervous system) via sensory neurons. In the spinal cord, the impulses are processed and a response is relayed back.
